I just did a 4 team moneyline parlay for the Bucs, Bills, Rams, and 49ers. This one site (I won't mention as it may break the rules) has a promo for one bet risk free up to 1k for new customers. The payout is like $2800. I threw it all on that. I'm not a big gambler but you get the money back in bets if you lose so I figured I could use 1k still to bet during the year if I lose this parlay.
